Tankless Water Heater Installation
Tankless water heaters provide endless hot water while reducing energy use by up to 40%. Ideal for homes and businesses, these units save space and last up to three times longer than standard tanks. Our certified technicians install Noritz and Rinnai models with warranties, ensuring energy efficiency and compliance with local building codes for both residential and commercial applications.
High-Efficiency Repairs
High-efficiency water heaters maintain optimal performance through specialized repairs. We service gas condensing, electric heat pump, and tankless systems, addressing leaks, thermostat failures, and sediment buildup. Our repairs extend system lifespan while maintaining compliance with current NAECA energy standards, ensuring reduced utility bills and environmental impact for Concord residents.
Emergency Water Heater Service
Emergency water heater services address urgent leaks, pressure issues, and gas line failures. Our team responds within hours to mitigate water damage, offering same-day repairs and free written estimates. We provide safety guidance for earthquake zones, including seismic gas shutoff valve installations, ensuring compliance with California safety regulations for residential and commercial properties.
Water Softener Systems
Water softener installations prevent mineral buildup in pipes and appliances. We offer Pelican and Nuvo systems for homes with hard water, reducing scaling in water heaters and extending equipment lifespan. These systems improve water quality for drinking, laundry, and bathing, providing long-term cost savings through reduced maintenance and energy consumption for Bay Area residents.
Recirculation Pump Installation
Recirculation pumps reduce water waste and delivery times by maintaining hot water in pipes. We install Grundfos and Armstrong models with timers, optimizing efficiency for homes and businesses. These systems conserve up to 12,000 gallons annually while improving convenience, particularly in large properties or drought-prone areas like Solano County.

Humberto came out on a hot Sunday afternoon--he was clearly knew what he was doing. He explained EVERYTHING to my husband and me. The problem with our leading water heater, the features in our new water heater, and how to operate our new one. He was quick, efficient, and very patient with my questions as he went along, and he added a pan under the hot water heater (which we did not have and it makes so much sense). My husband and I were thrilled with his effort, his customer service approach, and the excellent craftsmanship. I will recommend Humberto and this company to all my friends.

If I can give 10 star I would! I highly recommend Water Heater Master, that's how Diamond Certified work! My water heater stopped working last night and started leaking. I called and Spoke to Alex and I was really happy with his recommendation and came out the same day to replace it! Professional, Responsive and their prices were fair and Eddy the serviceman was extremely professional and had the job done in only a few hours and I was really impressed Eddy cleaned up after the job.
Could not have asked for more. These guys had a reasonable price and overall excellent company and great experience with their team. Really good job! Much better than Lowes, Home Depot or General Plumber! Thank you Alex and Eddy!

Fantastic experience - and saved me thousands of dollars. They will absolutely be my first call from now on. Another reputable company had come for an evaluation and recommended a solution exceeding $4k. I called Alex for a second opinion and he practically solved the issue over the phone. He still had a Rigo come out the next morning and resolved the issue within minutes - an issue the other company had not considered before recommending full replacement. It is so valuable to find a team you trust for their wisdom, capability and honesty. I highly recommend Alex and Water Heaters Masters

Solid five stars, from start to finish. they came out for the estimate on time and at no charge, were super helpful with scheduling and followup questions, arrived right on time for the install, cleaned up, got rid of the old unit and the two guys on the job were super friendly, professional and efficient. the final total honored the original quote to the penny. I got a few other estimates and they were all within a few dollars of each other so I feel this cost was reasonable. perhaps others would be as professional, but I am quite confident that you won't be disappointed with this team a huge shoutout to Water Heaters Masters!

Thank you Alex and the team at Water Heater Masters! After a failed delivery of a new water heater from another company, Mike came out the same day and had a new water heater in his van that I purchased. He removed the old one and installed the new one in about one hour. The new water heater works great, the installation looks good and everything was left picked up.

One of the properties I manage had a water heater failure during Memorial Day weekend. Lucky for the tenant, Water Heaters Masters was able to schedule the job on the same day. Jason came on site, went and picked up the new water heater from the store where I pre-ordered a water heater, and got the job done in 2.5 hours. Jason did the job quickly, carefully, meticulously, and masterfully. He is helpful, friendly, and very easy to work with. He clearly takes pride in his work. Thanks for a job well done! I will keep their number on my quick dial for sure. Highly recommended!

Water Heater Masters sent Jason to evaluate my water heater issue. My water heater was under warranty, so the manufacturer, Rheem, send a replacement part. The package Rheem sent contained only one of the two needed parts, so Jason installed the part that did arrive. After contacting Rheem again, and getting the second parts package, Jason came again, on a Saturday morning, to finish installing the parts installation, for no additional charge. You can't ask for better service.
